[BZ #2337]
2006-12-13 Ulrich Drepper <drepper@redhat.com>
[BZ #2337]
* libio/Makefile (tests): Add tst-setvbuf1.
* libio/tst-setvbuf1.c: New file.
2006-12-08 Jakub Jelinek <jakub@redhat.com>
[BZ #2337]
* libio/genops.c (__uflow): Fix a typo.
* libio/wfiledoalloc.c (_IO_wfile_doallocate): Don't stat
nor set _IO_LINE_BUF bit here. Size the wide buffer based on
the narrow buffer size.
2006-11-24 Jakub Jelinek <jakub@redhat.com>
[BZ #2337]
* libio/libio.h (_IO_FLAGS2_USER_WBUF): Define.
* libio/wgenops.c (_IO_wsetb, _IO_wdefault_finish): Test and set
_IO_FLAGS2_USER_WBUF bit in _flags2 instead of _IO_USER_BUF bit
in _flags.
* libio/wstrops.c (_IO_wstr_overflow, enlarge_userbuf,
_IO_wstr_finish): Likewise.
* libio/wmemstream.c (open_wmemstream): Likewise.
* libio/fileops.c (_IO_new_file_close_it): Call _IO_set[bgp]
even for wide streams.
